Not sure about this. Most JS frameworks only last a few years before the next shiny is mass adopted. The churn in JS land is insane.
React is definitely one of the long beards though, and thats’s because declarative programming is a win for UIs IMO. So much so it had a massive knock on effect in popularizing this approach (what’s old is new again… and again) across languages and problem sets.
IMO we're long past the churn era - Svelte itself is 8 years old. There are occasional bursts of new frameworks and tools, but only when there is a new niche - the last one I remember was a few years ago when suddenly everyone wanted to do a static website generator. And that didn't make existing frameworks obsolete.
In my post I was actually speaking about learning CSS and HTML alongside the "real programming language" that is JS/TS.
